A simulation environment for Autonomous Underwater Vehicles

OCEANS 2009-EUROPE, 2009
This paper gives an overview of the AUVFramework, a simulation environment for the evaluation of concepts regarding AUVs. An infrastructure of functionalities (maps, interface to kinematics, communication between multiple AUVs) supports the development of autonomous control.

Path Planning for Autonomous Underwater Vehicles

IEEE Transactions on Robotics, 2007
Efficient path-planning algorithms are a crucial issue for modern autonomous underwater vehicles. Classical path-planning algorithms in artificial intelligence are not designed to deal with wide continuous environments prone to currents. We present a novel Fast Marching (FM)-based approach to address the following issues. First, we develop an algorithm

Autonomous underwater vehicles localisation in mobile underwater networks

International Journal of Sensor Networks, 2017
Autonomous underwater vehicles AUVs form mobile underwater networks to conduct underwater surveying missions cooperatively. Due to the severe turbulence caused by water currents, individual AUV has to adjust its heading constantly to ensure reaching destination.

Autonomous Underwater Vehicle Navigation

IEEE Journal of Oceanic Engineering, 2010
This paper considers the vehicle navigation problem for an autonomous underwater vehicle (AUV) with six degrees of freedom. We approach this problem using an error state formulation of the Kalman filter. Integration of the vehicle's high-rate inertial measurement unit's (IMU's) accelerometers and gyros allow time propagation while other sensors provide

Autonomous navigation of underwater vehicles

IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002
The goal of the work is to propose a method to solve with visual means the problem of underwater navigation of an autonomous vehicle moving in deep sea in order to perform inspection of a pipe positioned near the ocean floor. We refer to the ability of an autonomous system to determine its motion with respect to the environment. It is well known that a

Development of autonomous underwater vehicles in Japan

Advanced Robotics, 2002
In the hope of expanding underwater observation and research, the Institute of Industrial Science (IIS) at the University of Tokyo started extensive R&D on autonomous underwater vehicle (AUV) in 1984. IIS has constructed nine vehicles, including three ocean-going vehicles, one lake survey vehicle and various testbed vehicles.

A formation flying algorithm for autonomous underwater vehicles

IEEE Conference on Decision and Control and European Control Conference, 2011
A control algorithm for the problem of formation flying for autonomous underwater vehicles is presented. Using a restrictive communication scheme and LQ optimal control, the control algorithm respects the limitations of underwater communication and on-board computing power.

Path Planning for the Autonomous Underwater Vehicle

2013
This paper introduces a novel method to find the optimal path for Autonomous Underwater Vehicles (AUVs). AUVs have gained importance over the last few years as service and research tools in a variety of applications. Path planning is one of the challenging tasks when dynamic obstacles are encountered.

Navigation of underwater autonomous vehicles

Proceedings of the 2000 International Symposium on Underwater Technology (Cat. No.00EX418), 2002
The paper suggests an approach to solving the problem of navigation of an underwater vehicle using acoustic and geometric data and gravitation field potential changing in time. The known methods of making seafloor acoustic maps are not effective for correction of coordinates in areas of smooth relief and in shallow water. The suggested algorithm allows
